Condusiv’s Diskeeper 16 Server with DRAM caching guarantees to solve the toughest performance problems on physical servers with faster than new performance, or your money back for 90-days – no questions asked. Instead of “defragging,' Diskeeper 16’s newest patented engine ensures large, clean contiguous writes from Windows so fragmentation is no longer an issue for HDDs or SSDs. This eliminates the “death by a thousand cuts' scenario of many, tiny writes that inflates I/Os per second, robs throughput, and shortens the lifespan of HDDs and SSDs alike. Diskeeper 16 electrifies Windows system performance to operate faster than new with the addition of dynamic memory caching – using idle DRAM to serve hot reads without creating an issue of memory starvation or resource contention.

Proactive and Efficient Server Performance OptimizationWhere typical defragmentation utilities consume resources to operate and deal with fragmentation only after the performance penalty has already been incurred, Diskeeper 16 is the only proactive solution that solves the problem in real-time while running transparently in the background, eliminating fragmentation issues from occurring on HDDs, SSDs, and SAN storage systems while also eliminating the IOPS inflation from many small writes and reads. Diskeeper 16 boosts performance faster than new with DRAM caching. The real genius in Diskeeper’s newest engines is that nothing has to be allocated for cache. Diskeeper dynamically uses only what is available at any given moment and throttles according to the need of the application. If memory is under provisioned and the application asks for all the memory, the caching engine throttles back entirely. However, with as little of 3GB of available DRAM, latency is reduced by an average of 40% on production workloads.

Diskeeper's intelligent resource monitoring, InvisiTasking®, ensures all optimization occurs without hampering system resources, so servers can operate at full production while Diskeeper 16 runs in the background. InvisiTasking monitors resource consumption on a Windows system (disk, memory, network and CPU usage) and uses only resources that are otherwise idle, so Diskeeper 16 runs invisibly with no intrusion on system resources. InvisiTasking monitors volumes for files that are impacting performance and deploys the Instant Defrag™ engine to consolidate the few remaining fragments on HDDs (SSDs excluded) that were not eliminated by IntelliWrite, if any. With Diskeeper 16 Server, optimization is proactive, continuous and seamless.

For IT professionals who need to deploy Diskeeper 16 across multiple servers, the Diskeeper 16 Administrator console allows for seamless network deployment. For Windows servers, Diskeeper 16 is the only highly efficient and proactive software for maximum performance—making it the #1 solution for keeping Windows servers running better than new.

IntelliWrite® - write I/O optimization technology prevents files from being fractured and broken apart into pieces, with each piece requiring its own I/O operation before being written to disk or SSD in a non-sequential manner. This stops the Windows phenomena of fragmentation from occurring before it becomes a problem.

IntelliMemory® read I/O optimization technology intelligently caches active data from read requests using idle server memory. This further reduces I/O overhead to the underlying storage device, enabling organizations to get more performance and life from the hardware they already have.

InvisiTasking® - intelligent monitoring technology allows all 'background' operations within the system to run with near-zero resource impact on current activities.

Benefit Reporting - displays the benefits provided to the system by revealing fragments eliminated and what that means to percentage of write and read I/O reduction and how much I/O time was saved on that system due to writing and reading files in a sequential state as opposed to fragmented state. It also shows the percentage of all read traffic that is cached from idle DRAM and what that means to time saved by serving reads from DRAM instead of the underlying storage device. See displays for free spaces consolidated and total I/Os removed from both write and read optimization and total time saved for any given period of time.

I/O Performance Monitoring - reveals key performance metrics like IOPS, throughput and latency. It reveals the amount of workload processed on the local system for any given time period. It also provides important memory usage information like total physical memory and min/max/avg of available memory and how much of that was used for cache. This helps administrators fine tune memory allocations to get the most from the IntelliMemory DRAM caching engine. If there is not sufficient available DRAM, users are not getting the best performance possible from Diskeeper.

Analytics - provides an hour-by-hour view for any time period to understand exactly what is happening on the local system related to key metrics like workload, read/write percentage, IOPS, throughput, I/O response time and benefits like write I/O reduction from IntelliWrite and read I/O reduction from IntelliMemory

Instant Defrag™ - technology has been enhanced to monitor volumes to resolve critically fragmented files in real-time that are known to cause performance problems, making it SAN-friendly. This feature is turned off in the event of solid-state drives. This is the perfect complement to IntelliWrite in the rare instance that not all fragments were eliminated in the first place.

Efficient Mode - in addition to an extensive defrag mode, Efficient Mode offers the greatest net gain in system I/O resource savings ever available. It immediately targets and eliminates only fragmentation that directly affects system performance that is on the system and Diskeeper automatically prevents most fragmentation after installation.

Free Space Consolidation Engine - swiftly consolidates free space and tightly integrates with Instant Defrag to handle new fragmentation as soon as it is created.

Network Management Support - ensures easy management of Diskeeper 16 settings and functionality across the network through the Diskeeper 16 Administrator edition or Group Policy.

Resource RequirementsDiskeeper 16 requires 250MB of available hardware space. IntelliMemory caching requires a minimum of 3GB of memory on the system and at least 1.5GB of idle, available memory before caching will initiate.

Additional Software RequirementsDiskeeper 15 Server requires .NET 4. If .Net 4 is not installed on your system, Diskeeper will attempt to download and install it for you. A reboot may be required due to the .Net installation.
